Abstract

The utility model relates to a wind passage and ice groove type natural cold storage type freezer. The wind passage and ice groove type natural cold storage type freezer is a freezer which is adjusted by natural climate, the refrigeration of the freezer does not use electricity, and the freezer can be used for the fresh keeping of fruits and vegetables all the year. The wind passage and ice groove type natural cold storage type freezer is mainly composed of a refrigeration room, a hot insulating layer, a wind passage, and an ice groove. The wind passage and the ice groove are arranged on the outer side and the bottom of the refrigeration room. Cold energy can be stored around the cold storage room in winter, and the temperature in the cold storage room can be controlled between-1 DEG C and 8 DEG C all the year. The wind passage and ice groove type natural cold storage type freezer provides a practical and economical refrigeration and fresh-keeping facility for wide countryside of a cold area. The practical and economical refrigeration and fresh-keeping facility can be automatically built and managed, the practical and economical refrigeration and fresh-keeping facility has simple structure, and the practical and economical refrigeration and fresh-keeping facility is good for storing and refreshing the agricultural and sideline products of fruits, vegetables, etc. on the spot.

Description

The cold storage naturally freezer of air channel, ice groove type

The utility model relates to a kind of air channel, ice groove type nature freezer, is only to utilize natural climate to regulate the freezer that just can throughout the year use.

At present, known artificial cooling freezer, its adjustment is undertaken by using the refrigerant condenser power consumption, and its capital construction requires high, and the operation and maintenance of refrigerator system has certain technical requirements, and needs to consume a large amount of electric energy, thus the cost height; A kind of natural freezer is to use heat-pipe apparatus to utilize natural climate to regulate to reach the cold-storage purpose, and the heat-pipe apparatus cost is also higher; Another natural freezer is to use forced ventilation to make in the storehouse water in the tank freeze the freezer of cold-storage, and it need expend certain electric energy, also has ask for something in control operation; In addition ice cube is put into freezer, this had both accounted for the freezer usage space, and ice-out influences the use of freezer again.Therefore, four kinds of freezers all fail in vast rural area to obtain to be extensive use of more than.The original clamp of northern country can only be done warm cellar for storing things in the winter time, can not use owing to temperature in the cellar for storing things is high during summer and autumn.

The purpose of this utility model provides the cold storage naturally freezer of a kind of air channel, ice groove type, its air channel, ice groove by having, utilize natural climate to regulate cold-storage and reach without consumed power equal energy source refrigeration, Keep cool, and there is lower temperature in the storehouse whole year, is used for the preservation and freshness of fruits and vegetables.

The purpose of this utility model is to realize like this, its primary structure comprises air channel (5) (6), ice groove (1), refrigerator (3) and thermal insulation layer (7), they all are built in underground (so not being suitable for the high area of level of ground water), air channel (6) (5) and ice groove (1) are built in respectively in the soil layer (11) of refrigerator (3) bottom and both sides, and air channel (5) (6) and refrigerator (3) are respectively with corresponding air inlet (2) (4) with there is the air outlet (8) of certain altitude to link.In the winter time, temperature is lower than in the refrigerator (3) or during the interior temperature in air channel (5) (6) outside the storehouse, under the effect of cold and hot air pressure difference, a cold air part is discharged by air outlet (8) by flow through air channel (5) in refrigerator (3) the both sides soil layers (11) of air inlet (4) again; Another part is entered in the refrigerator (3) by flow through air channel (6) in refrigerator (3) bottom solum (11) of air inlet (2) again, is discharged by air outlet (8) at last; Like this, heat in heat in refrigerator (3) both sides and the bottom solum (11) and the refrigerator (3) will be taken out of, be dispersed in the atmosphere and go, make relevant soil layer freeze, make the temperature in the refrigerator (3) remain on suitable (as-1 ℃～0 ℃) scope simultaneously again; In ice groove (1), add water before it cyclostrophic is warm gradually and it is freezed or directly put into ice cube, just formed one on every side at refrigerator (3) like this and held the embracing layer that a large amount of cold energy are arranged; After it cyclostrophic is warm, this freezing embracing layer will make the temperature in the refrigerator remain on a lower scope---be lower than 5 ℃～8 ℃.In the cold energy that is held all around at refrigerator (3) does not exhaust as yet, weather changes cold again, just can regulate the interior temperature of refrigerator (3) by gravity-flow ventilation again, and begin around it cold-storage in soil layer (11) again, go round and begin again, can make the interior annual temperature of refrigerator (3) remain between-1 ℃～8 ℃.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the A-A cross section structural map of embodiment Fig. 4 of the present utility model.Its structural form left-right symmetry.

Fig. 2 is the C-C vertical section structural map of air channel (5) between the refrigerator among Fig. 4.

Fig. 3 is refrigerator among Fig. 4 (a 3) B-B vertical section structural map.

Fig. 4 be among Fig. 1 the D-D horizontal profile overlook structural map.Its structural form left-right symmetry.

Among the figure, ice groove (1), air inlet (2), refrigerator (3), air inlet (4), air channel (5) (6), thermal insulation layer (7), air outlet (8), short air channel (9), passage (10), soil layer (11).

In Fig. 1, see in conjunction with Fig. 4, the utility model is built in underground four refrigerators (3) that have, have air channel (5) between the refrigerator (3) in the soil layer (11), have air channel (6) in the bottom solum (11) of refrigerator (3), have ice groove (1) in refrigerator (3) outside (front and back of the freezer) soil layers (11) respectively, the topped thermal insulation layer in freezer top (7).In Fig. 2, air channel (5) are made up of two-layer institute up and down, they respectively with air inlet (4) and air outlet (8) UNICOM, air inlet (4) and air outlet (8) have certain altitude poor, can make that air produces mobile under cold and hot differential pressure action in it.Cold air is entered by air inlet (4), and hot-air is shed by air outlet (8).In Fig. 3, air channel (6) and air inlet (2) UNICOM, and link by several standpipes and refrigerator (3), each riser upper can be provided with lid, is used to control intake; Refrigerator (3) Shang Jiaochu has short air channel (9) and links with air outlet (8), so that discharge the hot-air in the refrigerator (3) in the winter time.In Fig. 4, have three ice grooves (1) before and after the freezer respectively, four refrigerators (3) are linked by the passage (10) in the middle of being built in, the passage front portion has made the twice winter protection door, and the thermal insulation layer at freezer top (7) applies the scope of covering and extends ice groove (1) and air inlet (2) and 1.5～2 meters of (4) outer rim.The quantity and the size of freezer refrigerator (3) will be determined by actual needs, can be one, also can be many between.

Owing to adopt such scheme, this freezer is built simple, and is various informative, and use and management is convenient, and expense is cheap, and the rural area that is particularly suitable for cold district below the winter temperature-15 ℃ is agricultural byproducts such as preservation and freshness fruit, vegetables on the spot.
